MOTOR-VEHICLE.

SPECIFICATION forming part of Letters Iatent 0. 734,283, dated July 21,1903.

Application filed January 2, 1903- Serial No. 137,401. (No model.)

To all whom, it may concern:

Be it known that I, DANIEL H. PFAUTZ, a citizen of the United States,residing at Germantown, in-the county. of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inMotor-Vehicles, of which the following is a specification.

My invention has relation to a motor-vehicle ofthat type or classwherein two bicycles are coupled together and furnished with a motor toform a four-Wheeled motor-vehicle, and in such connection it relates tothe construction and arrangement of such a motorvehicle.

The principal object of my invention is to form from two ordinarybicycles by a simple and strong connecting structure a motor-vehiclewherein seats for the occupants are disposed side by side above aplatform forming a floor for the vehicle and to provide the vehicle thusformed with a motor and mechanism for transmitting the power of themotor to the driving-wheels of the connectedbicycles.

To this end my invention consists, first, in-

securing to the frame of each bicycle two verticle tubes or uprights andconnecting these two sets of tubes by cross-tubing forming a light butstrong connection between the bicycles and in supporting on thisconnection the motor and driving mechanism, as well as a platformforming the floor of the vehicle; second, to supportabove the floor ofthe vehicle thus formed two seats separated from each other by an aisleand accessible from the rear of the vehicle'loypassing onto and uponsaid floor; third, to provide in such a vehicle a shaft connecting thesprocket-wheels of the bicycles together and geared to a second shaft ingear with the motor, both shafts being sup ported beneath the floor ofthe vehicle; fourth,

to provide in conjunction with the shaft'c'on necting the sprockets ofthe bicycles together two momentum or fly wheels, each secured to shaft,and, sixth, to provide a steering mechanism of simple constructionwhereby both front or steeringwheels of the connected bicycles maytogether be turned to the right or left by a positive movement of asteering lever or wheel The nature and scope of my invention will bemore fully understood from the following description, taken inconnection with theaccompanying drawings, forming part hereof, inWliich- Figure 1 is a side elevational view of a motorvehicle embodyingmain features of my invention. Fig. 2 is an underneath plan view of thesame. Fig. 3 is a top or plan view illustrating in detail the steeringmechanism for the vehicle. Fig. 4 is a front elevational and detail viewof the clutch for throwing the driving mechanism into and out ofoperation. Fig. 5 is a front elevational view of the clutch andauxiliaryparts. Fig. (iisacross-sectional view of the clutch andadjacent gears, and Fig. 7 is a side elevational detail view of theband-brake.

Referring to the drawings, a and a represent the frames of two bicyclesof ordinary construction. To each frame a or a is se cured avertically-arianged upright b,located immediately in the rear of thefront wheel a of each bicycle. To each frame a or a is also secured avertically-arranged upright 19, located near the rear or driving wheel aof each bicycle. The lower ends of the two up rights I; are connected byone or more crossbraces (2 and the lower ends'of the uprights b aresimilarly connected by one or more braces 12 The uprights b and Handcrossbraces b? and b by preference are formed of bicycle-tubing. The,steering-headsa of the two bicycles are also connected by cross braces12, also preferably formed of bicycletubing. Upon the cross-braces b andb is laid a platform or floor (1, and upon this fioor is supported themotor 0 for the vehicle.

Supported by the uprights b or adjacent portions of a frame a or a is aseat f. The two seats f thus supported are arranged'side by side with aspace or aisle between them, so that the operator and passenger mayenter from the back of the vehicle and by walking upon the floor throughthe aisle may reach the required seat. Under one seat f the .wisesecured to the sprocket-wheels motor e is preferably located, whileunder the floor extends the shaft c, driven by the motor 0, the shaft 6carrying a gear-wheel c meshing with a pinion e driven by the motor c.The pedal-shaft of each bicycle is removed, and in their place ashaft a,connecting both sprockets e together, is substituted. This shaft 0preferably extends beneath the flooring d and is keyed or other- Thesprockets e are each connected by a chain c with a sprocket c on theaxle of a rear or driving wheel a of each bicycle. On the shaft 6 isloosely supported two gears g of high speed and g of low speed. Eachgear g or g carries a cup into which is adapted to fit one of thecone-shaped surfaces of a friction-clutch This clutch is splined to theshaft e between the cup-shaped portions carried by the gears g and g andmay be shifted on the shaft 6 so that a coneshaped surface willfrictionally engage either cup by the following preferred mechanism:Midway of the cone-shaped surfaces projects a flange g, engaged by twosets of rollers 9 supported in the end of a forked lever-arm g. This arm9 is pivoted, as at g ,i11termediate of its ends in a bracket orextension g projecting from and supported by the floor (Z. This brackethas a sector g, notched or toothed, as at 9 into the recesses of which apin 9 is adapted to slip. A handle and rod are arranged to control themovement of the pin, so that it may be wholly withdrawn from the notchesand the lever-arm g swung toward the right or left and then againpressed into a notch g to lock the arm in the required position. Amovement of the arm will through its forked end cause the rollers tothrow the clutch to the right or left to cause said clutch to engage orinterlock with either the high or low speed gear g or g. In the verticalposition the arm g releases the clutch g from both gears g org, asillustrated in Fig. 6. Each gear (7 and g normally travels idly on thesprocket-shaft 6* and conveys its rotation to said shaft only whencoupled to the clutch g, as hereinbefore described. The gear 9 of largerdiameter is geared with a gear 71. of small diameter, and the gear g ofsmall dianr eter is geared with a gear h of larger diameter. The twogears h and h are keyed to the shaft c, driven, as hereinbeforeexplained, by the motor 6. Upon the sprocket-shaft e is also secured afriction-disk It, around the periphery of which is placed the band It,adapted to be tightened or loosened by the movement of an arm or leverThe bandbrake thus formed furnishes an effective means for stopping therotation of the shaft 6 whenever the clutch g is thrown out ofengagement with both gears g and g. On the shaft e adjacent to eachsprocket e, but inside the two frames (4 and a, is secured a fly-wheelm. These two wheels min rotating serve by their momentum to steady thevehicle and to provide for the equal distribution of power to both endsof the shaft 6 The steering mechanism for the vehicle is constructed,preferably, as follows: In each head a oscillates the shaft 71, fromwhich the fork supporting the front or steering wheel 0. extends. Thetwo shafts n are each provided with an arm a, secured at one end to theshaft n and connected together at the other end by a link or. Upon thetop crossbrace b connecting the heads a together, is pivoted abell-crank lever n", one arm of which is slotted and engages a pin n,projecting from the link 12?, intermediate of the ends of said link. Theother arm of the lever 01 is connected by a link n with a handle a, piwoted at its lower end in a bracket of, supported upon the flooring. Amovement of the handle 11. toward or away from the operator will throughthe bell-crank lever n and link of cause the shafts n to turn to theright or to the left simultaneously.

To start the vehicle before the power is appliedto the sprocket-shaftc", as well as to propel the vehicle by foot if the motor and drivingmechanism should be disabled, there is provided a treadle mechanism ofthe following preferred construction: In a bracket 1), supported by thefloor (1, adjacent to the front uprights b, is pivoted a treadle-lever7), connected by a link 13 with an eccentric or crank pin 1) on a pinionor driving gearwheel 7). This gear-wheel p is keyed to a short shaft19", arranged in bearings underneath the floor (l, parallel with andadjacent to the sprocket-shaft 6 This pinion or gearwheel p meshes witha pinion p, keyed to the shaft 6 and by a reciprocating movement of thetreadle-lever p the gear 19 is rotated, thus turning through the gear 19the shaft 6 Having thus described the nature and object of my invention,what I claim as new, and desire to secure by Letters Patent, is-

1. In a motor-vehicle, in combination with two bicycle-frames, twovertical uprights sccured to each frame respectively adjacent to eachwheel, a flooring supported by said Vertical uprights and cross-bracesconnecting the steering-heads of the respective frames, a motorsupported upon the flooring adjacent to the rear or driving wheels ofthe frames, two sprockets supported respectively by the frames, a shaftconnecting said sprockets and supported below the flooring andintermediate gearing connecting the motor with said sprocket-shaft.
